TYPEWRITING MACHINE.

Application led November 2B, 1923. Serial No. 677,863.

To ZZ 207mm it may concern:

Be it known that I, MAX R. URBAN, a citizen of the United 'Sta-tes,residing in Elizabeth, in the county of Union and State of New Jersey,have invented certain new and useful Improvements in TypewritingMachines, of which the following is a speciication.

This invention relates to typewriting machines, and more articularly towork-websupplying and car on-carrying means therefor. More artieularl itrelates to typewriting mac ines of tie continuous billing class.

ln the continuous billing machine, as illustrated for example, in thepatent to Wernery and Smith, No. 1,132,055, provision is ordinarily madeof a long carriage-extension supported in part upon a rear eX- tensionof the machine frame, andhaving a track upon which a carbon-carrier isreciprocable toward and from the revoluble platen of the machine. Thework-webs have heretofore been introduced into the machine at the rearof the carriage-extension from stationary web-carrying rolls or othersuitable web-supplying means located to the rear of thecarriage-extension and generally at a substantial distance below it.

This arrangement of the web-.supplying means is open to severalobjections. lin order to make the web-supplying means accessible for thereplenishment of the web and for other purposes, it was necessary thatconsiderable space be provided at the back of the desk on which themachine was supported, and this was a drawback in crowded offices. Theweb-supplying means was not visible to the operator moreover, and henceone of the webs was apt to become exhausted without the operator-sknowing about it. This would result in the writing of one less copy thanintended until the fact vthat one of the webs had become exhausted wasdiscovered, when it would be necessary, of course, to rewrite the formor,

forms of which an insuiiicient number of copies had been made. Then,too, a stretch of slack -had yto he provided in each web between thestationary web-supplying means and the movable carriage-extensionbilling machine 1s supported to accommodate the relative movement ofthese parts, and these slack stretches of the webs, especially ifseparate narrow webs were employed, were apt to become disarranged, ortangled by the wind.

In accordance with the present invention, all of the above-mentioneddifficulties are overcome by the provision of a websupplying framemounted for movement from side to side with the carriageu This frame ispreferably mounted on the usual carriage-extension above thecarbon-carrier. `Web rolls may be mounted on the frame and arepreferably arranged in a horizontal row, so that all are visible to theoperator seated at the machine and are readily accessible for webreplenishment.v When the web upon one of the rolls is exhausted, theoperator can .observe the fact at once and can easily insert a freshweb-supply. The mounting of the web-supplying rolls to travel with thecarriage eliminates the need of the webs as the carriage travels fromside to side. A substantial economy of oltice space may be effectedalso, due to the fact that the desk upon which the continuous can beplaced back to back with another desk, or can be placed against thewall.

The webs areV directed by suitable guides from their supply rolls to therear .of the carriage-extension, and are thence led forward between theearbons of a carboncarrier reoiprocable toward and from the platen. Thecarbon-carrier may include the usual stepped frame, but the steps of thetrame, according to one method ofpracticing the invention, are not used.Brackets are detachably connected to the carboncarrier frame and bearcarbon-carrying rolls, each of which rolls is provided with carbon foractive use and also with a considerable reserve supply. Provision ismade of means for holding the carbon-carrying rolls against rotation inthe ordinary operation of the machine, but such means may be releasedwhen it is desired to replace a- Uli Vus

wornout stretch of active carbons with a fresh stretch.

It is a feature of the invention ,that the supports for thework-web-supplying rolls are adjustable toward and from each other toaccommodate diierent lengths of webrolls between them, and are alsoadjustable together to locate the web in line with different selectedfields of the platen. The carbon-roll-supporting brackets,too, areadjustable toward and from each other to accommodate carbon-rolls ofdifferent lengths in accordance with the width of the work-webs, and areadjustable together to locate the carbons in line with differentselected fields of the platen, the adjustments of thecarbonroll-supporting brackets being made to correspond to theadjustment of the supports for the work-web-supplying rolls.

In accordance with one feature of the invention, the web-supply .frameis detachably mounted upon the carriage-extension, and thecarbon-roll-supporting brackets are detachably mounted on thecarbon-carrier. The carbon-carrier frame has provision. as usual, forthe attachment of carbon-holding blades.

4It will be seen, therefore, that the machine may be quickly convertedfor doing fan fold work in the previously known manner.

The carbon-carrier mav be converted for.

fan-foldwork independently of the removal of the web-supply frame, and,conversely, the web-supply frame may be removed independently of theconversion of the carboncarrier.

Provision is made kfor changing the workweb in the machine at will, whena diiferent style or width is desired. The supports in which the ends ofthe web-supplying rolls are journaled are connected to each other tofrom a rigid truss, which is held to the remainder of the web-supplyframe by its own weight and the weight of therolls, and therefore may beremoved at will from the frame. The carbon-carrier is also detachablymounted on the carbon-carrier base. When it is desired to substitute inthe machine a web of a different width, or different in some othercharacteristic, from the web in the machine, the carbon-carrier and theweb-supplying rolls may be removed from the machine together withoutdisturbing the interleaved relation of the work-webs and carbons, and atruss bearing paper-webs of the desired width, together with acarbon-carrier having carbons of the desired width interleaved with saidwebs, may be substituted.

Other features and advantages will hereL inafter appear,

In the accompanying drawings,

Figure 1 is a sectional side elevation on the line 1--1 of Figure 4,showing a continuous billing machine having the present inventionapplied thereto.

Figure 2 is a detail lon itudinal vertical section on the line 2-2 oFigure 7, showing an end of the web-supporting truss, and its connectionto an end member of the web supply frame.

Figure 3 is a horizontal section on the line 3-3 of Figure 4, showing anend of the web-supporting truss.

Figure 4 is a transverse vertical section on the line 4.--4 of'Figure 1,looking toward (not shown) are depressed to swing types 10 upwardly andrearwardly to print against the front of a revoluble platen 11,l

journaled at its ends by a platen-axle 12 in a swing-frame 13 mounted onthe .traveling carriage 14 of the machine. The carriage 14 is movablefrom side' to side in the usual manner upon a front rail (not shown) anda rear' rail 15 supported by the machine frame 16. A rearcarriage-extension 17, comprising brackets 18, transverse rods 19 and 20and longitudinal rods 21, is mounted for movement with the carriage14being sup rted at the. rear upon a rail 22 mounted at t e rear of an,extension 23 of the machine frame 16. The carriage-extension 17 hasrails 24 upon which the base 25 of a carbon-carrier 26 is mounted formovement toward and from the platen 11. At line-spacing, thecarbon-carrier 26 advances toward the platen with the workwebs A andcarbons B. When the typing of a stretch of webs is completed, theswing-frame 13 is displaced to raise the platen 11 and thereby to permitstraightening of the-carbons B; the work-webs A are drawn forward to agage 27; and the carbon-carrier 26 is thrust to the rear to withdraw thecarbons from the completed section of web A. The platen 11 is thenrestored to normal position and the completed web-section is severed bymeans of a knife 28 located at the front of the platen. As thus fardescribed, the machine is like the Wernery and Smith machine referred toabove.

In' accordance with the present invention, provision is made of awork-web-supply frame, which is mounted on the carriageextension 17 formovement therewith from side to side of the machine. This frame consistsprincipally of upright end members 29 and 30, mounted, respectively, atthe front and rear of the carriage-extension 17 and a connectingroll-supporting truss 31. The end members 29 and 30 are in the form ofinverted Us, the forward member 29 consisting of vertical legs 32 and ahorizontal body 33, and the rear member 3() consisting of vertical legs34 and a horizontal body 35.

The -lower ends of the legs of the end members 29 and 30 are detachablyconnected to the carriage-extension 17, the arrangement being such thatthe web-supply-frame may be quickly removed from the machine. Each leg32 of the front upright. frame member has its lower end curved topartially embrace the front transverse rod 19 of the carriage-extension17, and is provided with a complementary clamping jaw 36, which may bedrawn forcibly toward the leg 32 by turning a knurled headed screw 37,threaded into the leg 32, to cause the jaw to co-operate with the leg toclamp the leg firmly in upright position upon the rod. Each leg 34 ofthe rear end member has a -pin 38 projecting from it. which is receivedin a clamping plate 39 to correctly locate the latter. A knurled headedscrew 40 passes through the 'clamping plate between the transverse rod.20 and another-transverse rod 41 commonlv provided at the rear of thecarriageextension 17 for web-guiding purposes, and is threaded into theleg 34 of the rear end member 30. The screw 40 may be turned to draw theclamping plate 39 toward the leg of the end member to clamp the endmember securely in uprightposition.

The weblrollsupporting truss 31 consists chiedy ot' a leftweb-roll-bearing side member. 42 having inturned ends 43 and 44 and aright web-roll-bearing side-member 45 having inturned ends 46 and 47.The rear inturned ends 44 and 47 of the side members 42 and 45co-operate to form the rear end of the truss 31. and the forwardinturned ends 43 and 46m-'operate to form the forward end of the truss.'lihe inturned endsv of the side members are connected to each other,with provision for widthwise adjustment of the truss to enable the trussto be used with web-rolls of different lengths. A headed screw 48 passesthrough an elongated slot 49 in the inturned end 44, and isl threadedinto the inturned end 47, and a similar screw 50 is received in anelongated slot 5l in the inturned end 47. and is threaded into theinturned end 44. One or both of these screws 48 and 50 may be tightenedto secure the end members 44. and 47 against relative movement. Theforward inturned end members 43 and 46 are similarly connected to eachother by screws 52 and 53. llach of the forward inturned ends 43 and 46is provided with a hook 54 to extend forwardly and downwardly to interitwith one of a series of notches 55 in the horizontal body-portion of theforward frame end member 29, and each of the rear inturned ends 44 and47 is provided with a similar hook 54 to extend rearwardly and Idown`wardly to interfit with one of a series of notches 55 1n thebody-portion 35 of the rear frame end member 30. A considerable numberof these notches 55 is provided, so

that various widthwise adjustments of the truss 31 may be accommodated,and so that the truss may be positioned in line with various fields ofthe platen.

The side members 42 and 45 o-f the truss 31 have downwardly andrearwardly extending slots 56 in their uppersides, the lower ends ofwhich form bearings for shafts 57 of the work-web-supplying rolls 58.One of these web-supplying rolls 58, as shown in Figure 6, consists of aspool 59 of web, wound on a hollow core 60 which is 'placed upon a coremember 61 mounted on the ,roll-shaft 57. Arms 62 extend downwardly fromthe side members 42 and 45 between the ends thereof, and have downwardlyand rearwardly directed slots 63, which receive and form bearings forthe 'ends of a web-guiding roll 64. Similar arms extend downwardly fromthe side members 42 and 45 adjacent their rear ends, and have downwardlyand forwardly directed slots 66, which receive and form bearings for aweb-guiding roll 67. The

work-webs are unwound from the rolls 58 by rotation thereof in acounterclockwise'direction, and are led to the rear over the guide-roll64, thence around the guideroll 67 and forward through the carboncarrier26 to the platen 11.

The carbon-carrier 26 reciprocates toward and from the platen in theusual manner, but embodies in its construction several features ofnovelty. The usual carbon-carrying blades are not used although theusual provision is made for their attachment, but

instead there are attached to the carboncarrler two co-operatingcarbon-roll-supporting brackets 68. Each bracket 68 comprises atransversely-extending portion 69 by which it is attached to thecarbon-carrier frame 70, a rearwardly-extending portion 71 for bearingthecarbon-rolls 72, and an inturned web-guiding finger 7 3 for holdingthe uppermost work-web A down to the carbon-carrier. y. Thetransversely-extending portions 69 of the brackets 68'have' elongatedslots 74ytl1erein, and through each ot these slots therepasses'a screw75 that is threaded into. the rear ofthe carbon-carrier frame forsecuring the bracket thereto. lThe brackets 68 mav be adjusted towardand from each other by reason of the screwand-slot mounting to vary theJdistance between the bearing portions 71 of the brackets to provide forcarbons of `different widths v corresponding to the different widths ofwork-webs used. rllhe rearwardly-extend ing bearing portions 71 of thebrackets 68' have open-ended slots 76 which form bearl nut 82draws theshaft 77 lengthwise, causing ythe flange 78 to bear against the end 79of therarbon-paper spool and force the other end of carbon-spool 72against the washer 81. This. pressure secures the carbon-spool 72against rotation relatively tothe washer 81, and the pressure of thewasher against the bracket 68 prevents rotation of the washer, so thatthe carbon cannot be unrolled whenl the nut I82 is turned up tight.tions 71 of the brackets 68 are upwardly inclined, so that thecarbon-rolls 72 are arranged conveniently to have the work-webs vA ledforward between them.. Whena stretch of carbon is used up. the nuts 82are loosened and the forward ends of the carbons are held stationarywhile the carboncarrier is retracted, to unwind a fresh formlength ofcarbon. The used up stretch of carbon is then severed with a ytypedworkweb section and the nuts 82 are tightened to again secure the carbonagainst unwinding.

The carbon-carrier frame 70 to which the bracketsV 68 are attached isdetachably mounted on the base 25 in the manner disclosed in the patentto Benjamin P. Fortin, No. 1,237,319, granted August 21, 1917. Thecarbon-carrier frame 7 0 with its carbonrolls 72 and the web-supportingtruss 31 with the work-web rolls 58 may be removed from the machinetogether therefore. without disturbing the interleaved relation of thecarbons B and work-webs A, and may be replaced bya web-supporting trussand a carbon-carrier having webs of a different style or widthinterleaved with carbons of an appropriate width. Unless the workwebs Aare quite narrow, the weight of the web-supplying rolls 58 willbe-considerable, and their inertia is apt to cause the Work to sliprelatively to the platen 11 -at line-spacing andso to cause irregularffline-spacing. Provision is made of a clamp 83. therefore, for drawingthe work-web A forward with the carbon-carrier 26, preparatory totyping, to create a slack in the work-web atv the rear of thecarbon-carrier, so that the rotation of the web-rolls 58 at line-spacingwill bel unnecessary. This clamp may be like the one disclosed in thepatent to Smith, No. 1,364,819, granted January 4, 1921. It comprises astationary lower jaw 84 on the car- The rearwardly-extending por-vbon-carrier frame to underlie the workwebs A and carbons B and a.swinging upper jaw 85 extending above the work-webs and carbons andpivoted :1t-86 on the carbon-carrier frame .70. vA spring 87 normallydraws the swinging jaw 85 down to effective position, and a bell-crank88, pivoted on the carbon-carrier handle 89, may be moved by a clamphandle 90 slidingly mounted on the carbon-carrier handle 89 to renderthe swinging jaw 85 ineffective. The drawing forward of thecarbon-carrier 26, while the clamp 83 is effective, draws the web A fromthe web-rolls 58 around the guide-roll 67. As the carbon-carrier 26.again moves to the rear, a slack is formed between the guide-roll 67and the carboncarrier', which is drawn upon at the subsequentline-feeding of the work. This slack is not permitted to fall at randomwhere it may catch upon stationary parts of the machine or otherobjects, as it travels from side to side with the carriage, but issupported upon the movable carriage-extension 17, the longitudinal rods21 of the carriageextension forming a table or frame for supporting theslack..

Variations may be resorted to within the scope of the invention, andportions ofthe im rovements may be used without others.
